ISM-2000 Infrared Photoelectric Multiplexer

Manufacturer: Pantron Instruments, GmbH
Category: Infrared Photoelectric Multiplexers

2-channel multiplex amplifier with manual and automatic gain settings. The PANTRON multiplex process guarantees a strict channel separation, even if the two light barriers are mounted very closely. Two level settings allow the multiplexer to be adjusted to overcome distance and other conditions.

Features and Specifications

  • Detection range up to 30 m (98ft)
  • Sensitivity for each channel adjustable with a potentiometer or automatically
  • One Semiconductor-relay output for each channel
  • Switching mode light / dark selectable for each channel
  • Sensor failure monitoring
